Starting voxel engine test...

Testing spatial index calculation...
 index(0,0,0) should be 0
 index(7,0,0) should be 7
 index(0,7,0) should be 56
 index(0,0,7) should be 448
 index(7,7,7) should be 511

Testing VoxelMath bitwise operations...
 setFilled(true) works
 raw value after setFilled should be 1
 setPointType/getPointType works with value 7
 raw value after setPointType(7) should be 0xF
 setTextureId/getTextureId works with value 1234
 texture bits are set correctly
 setVisibleFaces/getVisibleFaces works
 visible faces bits are set correctly
 setFilled(false) clears the bit
 raw bit 0 is zero after setFilled(false)

Testing chunk creation and voxel insertion...
 all inserted voxels have correct bitmask data
 voxel outside block should be zero (empty)
 empty voxel isFilled should be false
 empty voxel point type should be 0
 empty voxel texture ID should be 0
 empty voxel visible faces should be 0

Testing ChunkManager...
 chunk initially not present
 createChunk returns a Chunk instance
 getChunk returns the same instance
 chunkCount is 1
 chunkCount is 2 after second chunk
 removeChunk returns true for existing chunk
 chunk removed from manager
 chunkCount decremented after removal
 clearAll removes all chunks

All tests passed successfully!
